A most certaine and true relation of a strange monster or serpent found in the left ventricle of the heart of John Pennant, Gentleman, of the age of 21 yeares
A 1639 London pamphlet printed by George Miller, attributed to Edward May, recounting a case of a worm-like parasite found in the left ventricle of a 21-year-old gentleman's heart, written as a plain report for readers of the period. The three pictures are letter-led woodcut initials with ornate scrollwork and a single anatomical woodcut of a split heart showing a coiled serpent, offering a designer strong examples of dense black line, floral initial frames, and cutaway diagram drawing.
